CORN -PLANTER.

EBPECIFICATION forming part of Letters Patent No. 361,924, dated April 26, 1887.

Application filed January 12. 1887. Serial No. 224,136. (No model.)

To all whom, it may concern.-

Be it known that I, Lawson L. BROOKS, of

Knoxville, in the county of Knox and State of Tennessee, have invented certain new and useful Improvements in Corn-Planters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to whichit appertains to make and use the same, referencebeing hadto the accompanying drawings, which form a part of this specification, and in which Figure 1 is a longitudinal vertical sectional view of my improved corn-planter. Fig. 2 is a top view of the same with the seed-box removed, and Fig. 3 is a bottom View of the seed-box.

Similar numerals of reference indicate corresponding parts in all the figures.

My invention has relation to that class of seed-planters in which a disk having a number of perforations or seed-cups is revolved by the revolution of the drive-wheel bringing one of the cups to register with the seed-tube at the time; and it consists in the improved construction and combination of parts of such a planter, as hereinafter more fully described and claimed.

In the accompanying drawings, the numeral 1 indicates the frame of the planter, which is provided with two rearwardly-projecting bars, 2, between which the drive-wheel 3 is journaled with its axle 4, and the handles 5 are secured with their forward ends to the forward portion of the frame, and have suitable braces, 6, supporting their rear portions.

The drive -aXle is formed with a double crank, 7, upon which the rear end of a springpawl, 8, is pivoted, the forward end of the said pawl having a hook, 9, with which it engages the ratchet teeth upon the periphery of the seed-disk 11, which disk is journaled at its center upon a vertical stud, 12, at the middle of the machine-frame. This disk is formed with a circular series of perforations, 13, or seed-cups, and the ratchet-teeth in its periphery are engaged by a spl'ingpawl, 14, which prevents the disk from revolving backward.

The upper face of the seed-disk, is raised above the ratchet-teeth, and this raised portion fits into acircularaperture, 15, in theseedbox 16 in the bottom 17 of the same, and this aperture is covered at its forward portion by means ofa flange, 18, having a brush, 19, projectingdownward and sweeping over the seedcups.

The seed-box is secured to the frame by means of lips 20 at both sides of the frame, which lips project from the frame and are secured to the sides of the box.

The seed-tube 21 registers with its upper end with a perforation, 22, in the frame,which perforation registers with the seed-cups in the disk, and the upper end of the tube is provided with a plat-e or block, 23,which is hinged to the under side of the frame with its rear end, and has a slot, 24, in its forward end, through which a staple, 25, upon the frame projects, having a pin, 26, projecting through it and securing it in place. The lower end of the seed-tube is provided with asuitableopening-shoe, 27, for opening the furrow.

The inner side of the rim of the drive-wheel is provided with a block or bulge, 28, which may be brought to register with a suitable 7 5 starting-mark in the field, for the purpose of checking the hills planted, as will be more fully described. 7

It will now be seen that as the machine is propelled across a field the shoe will open a s furrow and the revolving wheel will reciprocate the springpawl, which will slide forward, and thereupon on its returnstroke carry the disk around one tooth, the hook engaging one ratchet-tooth at the time, and the spring-pawl 8 5 at the other side of the disk will stop the disk and prevent it from being pushed forward when the spring pitman or pawl is pushed forward. One hill will thus be planted at each revolution of the wheel; and it will be seen that if the planter is started with the bulge in the wheel above a starting-furrow and the row ended when the bulge is down, a furrow may be drawn from the point Where the planting stopped, so that the hills will be nearly in a line transverse to the furrows if the machine is started with the bulge above one of thesestarting-furrows at each end of the field.

The entire machine is simple of operation, not liable to become broken or injured by use, 10o

and if in any way inj ured it may easily be repaired without requiring any very skilled labor.

If the pin securing the forward end of the seed-tube is made of wood, this pin may serve as a break-pin, breaking if the tube and shoe strike an obstruction, and thus saving the tube and shoe.'

Having thus described my inventionfl claim and desire to secure by Letters Patent of the United States In a corn-planter, the combination of a frame provided with an aperture in its middle, and having a drive-wheel journaled in its rear end upon a crank-shaft, a lip at each side of the frame, a seed-box secured between said lips, the bottom of which is provided with an aper ture and abrush, an apertured disk between said bottom and said frame and having ratchet-teeth around its periphery, a seed-tube having a block at its upper end, said block being hinged to the frame at its rear end and provided with a slot at its forward end, a stapie upon the under side of the frame, a pin, a rod secured to said shaft having a hook at its opposite end, and a spring-pawl adapted to engage with said disk.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
